Removing index column in pandas when reading a csv

df.reset_index(drop=True, inplace=True)

When writing to and reading from a CSV file include the argument index=False and index_col=False, respectively. Follows an example:

To write:

 df.to_csv(filename, index=False)

and to read from the csv

df.read_csv(filename, index_col=False)  

This should prevent the issue so you don't need to fix it later.
